I've also done this conversion. Couple of things I can add.
When taking the brass end fitting off the chrome pipe that goes into the regulator, you may find it is on extremely tight. I had to take ours into a machine shop to get taken apart.
When removing the brass fitting, do not let the little spring inside go flying out because you may never find it again. This is for the check valve and you MUST re-install it.
If you are using a longer hose like a 20 footer, go with the 3/8" dia. size instead of the 1/4" one to minimize pressure drop. I would get the type of hose that has the more flexible rubber jacket as it's much easier to coil up or lay on the ground.
You may end up having to go to several stores to get all the fittings you need - I did. I found the best local place for fittings to be a hardware store that has an excellent stock of fittings for BBQs. A plumbing wholesaler would also be good.
If you're not familiar with gas fittings, I'd put some soapy water on them to check for leaks.
